“…Hasak and Hasmer sheep were polled breeds. There was a fossa structure in Hasak and Hasmer sheep in the anterior part of the sutura coronalis, at the level of the os frontale where horn protrusions were found in Anatolian wild sheep (Yalçın & Lök, 2009).…”

The aim of the study was to investigate the head structures of two domestic sheep breeds (Hasak and Hasmer) in Turkey. Gender neutral eight adult Hasmer sheep of 45-66 kg and eight Hasak sheep breeds of 43-66 kg obtained from Bahri Dag˘dasI nternational Agricultural Research Institute were used in this study. Measurements were made using digital caliper from 40 points on the skulls of both species. The skull of Hasmer sheep (265.56 ± 14.08) was longer than the skull of Hasak sheep (262.86 ± 9.65). However, the length of the arcus alveolaris maxillaris (77.01 ± 5.08), the length of the molar teeth (50.81 ± 1.22) and the length of the premolar teeth (26.16 ± 4.62) of Hasak sheep were compared to the Hasmer sheep (71.59, ± 5.25; 47.99 ± 3.64; 24.03 ± 3.76, respectively) was observed to be greater. According to these findings, although the skull length of Hasak sheep was shorter than that of Hasmer sheep and arcus alveolaris maxillaris in which molar and premolar teeth were placed was longer. In Hasmer sheep the values of greatest breadth of the foramen magnum, height of the foramen magnum (basion -opisthion), greatest neurocranium breadth-greatest breadth of the braincase (euryon -euryon) were higher than those of Hasak sheep. The difference between these values was also statistically significant (p <0.05). The lateral length of the premaxilla (nasointermaxillare-prosthion) parameter measured between these two species was statistically very important (p <0.01). In conclusion, in this study craniometric values depending on skull morphology of Hasmer and Hasak sheep which accepted as native breeds of Turkey were tried, to reveal similarities and differences with other sheep breeds in both amongst themselves.

“…Therefore, the number of supraorbital foramina could be an element to consider during surgical procedures or local anaesthesia (Audisio et al, 2011). On the other hand, in ruminants, during the exploration of the infraorbital nerve as part of the regional anaesthesia procedure, the facial tuberosity is the bone eminence most frequently used as a reference point ( N. infraorbitalis ; Audisio et al, 2011; Clarke & Trim, 2013; Hall et al, 2000; Yalçin & Lök, 2009). Given the absence of facial tuberosity in the Patagonian huemul deer, it is pertinent to palpate the infraorbital foramen, which houses the infraorbital nerve and its branches.…”

Studies of the normal skull anatomy of the Patagonian Huemul deer are scarce.Currently, the findings of bone lesions in the skull associated with metabolic imbalances are frequent in the literature. The objective of this study was to provide anatomical and morphometric data of the cranium and facies including a morphofunctional interpretation as a reference for clinical, ecomorphological and educational purposes.Five skulls were described, measured, scanned and digitally reconstructed. The presence of a caudal projection of the vomer bone, the absence of the facial tubercle and thin bones forming the cranial cavity were observed. Linear measurements allowed the skull to be classified as dolichocephalic, hyperlepten and ultra-dolichocranial. In conclusion, the Patagonian Huemul has a long head, an extremely long skull and a very narrow face. The thickness of the bones that made up the walls of the cranial cavity suggests chronic metabolic imbalances in response to mineral deficiency. The anatomical and morphometric data obtained in this study strongly emphasizes the relevance of considering the implementation of such management policies that aim at promoting an optimal nutritional context.

“…Similarly, with linear morphometric studies of the skulls of different species are made many geometric morphometric studies to evaluate the shape of the skulls and to indicate the sexual dimorphism (Dalton et al, 2017; Drake, 2011; Gündemir, Özkan, et al, 2020; Gürbüz et al, 2020; Kistner et al, 2021; Pares‐Casanova et al, 2020; Szara et al, 2022; Yalçin & Kaya, 2009).…”

This study aimed to explain the sex determination of the autochthonous dog Deltari Ilir with both morphometric and geometric analysis methods. For this purpose, 24 Deltari Ilir dog skulls (12 females and 12 males) were used in the study. The difference between males and females at 6 values was statistically significant. The most statistically significant difference was seen in the measurement of the greatest breadth of the occipital condyles (p < 0.000). This measurement was higher in male skulls. The next most significant difference was seen in the greatest inner height of the orbit measurement (p < 0.002). This measurement was also higher than for females. In general, the skull length measurements of male dogs were higher than that of females. Male dog skulls had greater skull length and skull height. The lateral view was used for geometric analysis and 14 landmarks were determined. As a result of principal component analysis, 22 PC values were obtained. PC1 accounted for 23.73% of the total variance. As a result of canonical variants analysis, it was observed that males and females were completely separated from each other. The caudal part of the males was wider than the females in geometric analysis. As a result of the study, sex‐determining characteristics were revealed for the Deltari Ilir dog. It was seen that gender analysis could be done with both morphometric and geometric analysis methods. In addition, it was seen that morphometric results and geometric analysis results supported each other. Moreover, the results of the study will be useful in the function of comparative anatomy, in veterinary clinical practice, in zooarchaeology but why not also in the veterinary forensic investigation.
